Former Mayor Ken Livingstone isn't surprised either, saying: "In the context of Boris Johnson's well known past comments, abandoning the central message of Rise as Europe's biggest anti-racist festival, and now this enforced resignation of his Deputy Chief of Staff, the real culture of the Johnson administration is becoming clear - one totally at odds with the needs of London as the most diverse city in the world."
